A key factor in the Union victory at Gettysburg was the Defensive position.

Under the command of General George Meade, Union forces occupied vital high ground, including Cemetery Hill and Little Round Top, which offered a substantial tactical edge. This elevated landscape allowed Union artillery and infantry to successfully fend off Confederate attacks and cause significant casualties. The robust defensive positions helped Union troops remain organized and resilient in the face of continuous assaults, playing a crucial role in their victory during the three-day battle and altering the course of the Civil War.
